Lep-Q Technologies LLC ("Lep-Q," "we," "us," or "our") operates Sensemaker, a read-it-later and knowledge management application available at https://sensemaker.app (the "Service"). These Terms of Service ("Terms") govern your access to and use of the Service.

By creating an account or using Sensemaker, you agree to these Terms. If you do not agree, do not use the Service.

You must be at least 13 years old to create an account.

You retain ownership of all content you save, create, or upload to Sensemaker. This includes articles you save, highlights you create, notes you write, tags you define, and documents you upload.

3.2 License to Us​

By using the Service, you grant Lep-Q a limited, non-exclusive license to store, process, and display your content solely for the purpose of providing the Service to you. This includes:

  • Storing your saved articles, highlights, and documents

  • Content that violates applicable law

We reserve the right to remove content or suspend accounts that violate these restrictions.

4. AI Features and Data Processing​

4.1 How AI Processes Your Content​

When you are a subscriber, Sensemaker uses AI (currently Claude by Anthropic, with support for other providers) to:

  • Generate summaries of content in your library
  • Classify and tag content by topic
  • Identify semantically connected passages across articles

4.2 AI Data Handling​

  • Your content is sent to the AI provider for processing and is not retained by the AI provider beyond the immediate request
  • AI-generated outputs (summaries, tags, suggested highlights) are stored in your Sensemaker account
  • AI processing only occurs for subscribers who have the relevant features enabled
  • You can disable AI auto-tagging in Settings at any time

4.3 No Training on Your Data​

Your content is not used to train AI models. It is processed only to generate outputs for your personal use within the Service.

5. Subscription and Billing​

5.1 Pricing​

The subscription is $8 per month, billed monthly through Stripe. Pricing may change with 30 days' notice to existing subscribers.

5.2 Payment​

Payment is processed by Stripe. We do not store your credit card number. Stripe's terms apply to payment processing.
